Produced a pretty bug while changing some old graphics code. :)

The sun rising over the alps. Another shot from my over-engineered #rustlang hill shading path tracer. I didn't properly account for the curvature of the earth but I think it looks quite pretty. :)
The DEM used is ASTGTM v003.

Having a bit of fun over engineering hill shading by path tracing digital elevation maps with an atmospheric simulation. (:
Coded in #rustlang and running on the CPU. Very slowly.

Made a little GPU particle system with @threejs. 16'777'216 particles dancing in a force field. Somehow completely forgot how much I enjoy playing with particles. :)

Coded a little toy for the @BevyEngine jam #2. If you've ever wanted to drift a combine harvester, this one is for you. ;) Mostly an exercise to learn rust and play with bevy. itch.io/jam/bevy-jam-2/rate/…

A rainy saturday seems like a perfect day to release a new version of simplex-noise.js and a little demo to go along. 29a.ch/sandbox/2022/simplex-… canvas 2d only, #nowebgl, not exactly fast as a result. :)

Just stumbled over an ancient project that @29a_ch and I had started. It would need much more work, but I think its kinda addicting: 29a.ch/ubercharge/ #js #gamedev

Today's project: updating redblobgames.com/maps/terrai… with a new version of simplex-noise.js from @29a_ch <github.com/jwagner/simplex-n…>
New JS (min gzip) is even smaller than before. Under 10kb. No, that's not for the noise library. That's for the *entire* page, including the library!

A bit more weekend #3Dprinting fun. Built a tool to apply procedural wood displacement maps to 3d prints using #threejs. 29a.ch/sandbox/2021/3d-print…
Hacky code but I find the results rather nice. Samples printed with @Polymaker_3D PolyWood on a @Prusa3D Mini .

A bit of 3d printing fun for a rainy sunday. Designed and printed a lens hood that creates swirly bokeh (the out of focus bits) via mechanical vignetting. At 15 min to print and 20 cents of materials a fairly cheap photo toy.

I hacked together a little js library for fitting gradients to images and extracting their primary colors. Curious to see whether people will find a use for it. Feedback is of course always welcome. :)

Just having a bit of silly fun way over engineering image dithering using simulated annealing. :) Demo: 29a.ch/sandbox/2020/dither-a…

Another gorgeous #PlayRaw from our friend @29a_ch of a ridiculously charmed view from the Alps and the setting sun. Come get the #raw and show us how you'd process this incredible view!

Forensically can now extract and identify some more JPEG data like quantization tables to identify forgeries. :)
